Top SchoolSam Rothstein is a software engineer based in San Francisco with seven years of experience building full-stack and front-end applications across mapping, autonomous vehicle, and research domains. He contributed substantive fixes and tests to CesiumJS—an influential open-source 3D mapping library—improving how unsupported 3D Tiles extensions are detected and handled. At Motional he worked on web-facing systems for an AV company, and his earlier research roles at UPenn and Swarthmore reflect strong foundations in computer graphics and applied mathematics. Currently at Shepherd, he combines practical production engineering with a habit of polishing documentation and build configurations, as seen in his CesiumWebpack and Cesium contributions. Collected experience across startups, large teams, and academia gives him a knack for turning complex spatial and systems problems into robust, well-tested solutions.
